Abstract

The invention provides a microwave device and a control method thereof. The microwave device comprises a high-voltage generation module, a pulse waveform generation module, a magnetic field generationmodule and a microwave generation module, wherein the high-voltage generation module is used for generating high-voltage pulse; the pulse waveform generation module is used for generating current pulse of a preset waveform; the magnetic field generation module is used for converting the current pulse into magnetic field pulse; and the microwave generation module is used for receiving the high-voltage pulse from the high-voltage generation module and the magnetic field pulse from the magnetic field generation module so as to output microwave pulse. The microwave device comprises multiple powermodes and can provide the microwave pulse with basically constant peak power in the multiple power modes.

Description

technical field [0001] The invention mainly relates to the field of microwave generation, in particular to a microwave device suitable for a linear accelerator and a control method for the microwave device. Background technique [0002] Image Guided Radiation Therapy (IGRT) is a radiotherapy device that images patients before or during treatment, and adjusts the treatment position and treatment conditions based on the imaging results. Generally speaking, the same linac is used in IGRT to generate the imaging beam and the treatment beam, the imaging beam is usually lower than 3MV, and the treatment beam is usually higher than 6MV. The current scheme for generating the imaging beam is: reduce the microwave power output by the microwave device, and increase the intensity of the injected electron current to obtain an imaging beam of about 2MV. [0003] In low-energy IGRT, the microwave device of the linear accelerator is mostly a magnetron. The basic principle of the magnetron...
